It measures 1.625 inches inside diameter, 1.875 inches outside diameter, and 0.125 inches thick with a round cross section. Rated at 90 durometer (extra hard), this O-ring handles operating temperatures from -40 degrees F to 250 degrees F. Sold in a pack of 50, it suits shops and service technicians who stock seals for recurring maintenance work. Buna-N is the most widely used O-ring elastomer in the trades and is the standard choice wherever petroleum-based fluids are present.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for residential and light commercial applications involving petroleum-product media, including hydraulic systems, pneumatic fittings, refrigeration service valves, and plumbing shut-off assemblies. The 90-durometer hardness rating makes it well suited for higher-pressure environments where compression set resistance and abrasion resistance are priorities. HVAC technicians, plumbers, and fluid-system mechanics regularly stock Dash 223 seals for service calls requiring fast seal replacement without custom sourcing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction — excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n\u003cli\u003e90 durometer extra-hard rating for high compression set resistance and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eOperating range of -40 degrees F to 250 degrees F suits a wide range of service environments\u003c\/li\u003e\n\u003cli\u003eRound cross section, 0.125 inches thick, Dash 223 standard sizing for easy cross-referencing\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003ePack of 50 units — practical quantity for shop stock or fleet service inventory\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum-product media per manufacturer specification. Designed as a Dash 223 standard O-ring replacement for use in any system calling for a 1.625-inch ID, 1.875-inch OD, 0.125-inch thick Buna-N seal. Not FDA approved; not intended for food-contact or potable-water applications. Store away from direct sunlight, ozone sources, and electrical equipment that may generate ozone.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eShut off and depressurize the system fully before removing any fitting or valve cap that retains this seal. Clean the groove and mating surfaces before seating the new O-ring to prevent contamination-driven leakage. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before installation to ease seating and reduce the risk of tearing during assembly. Installation should be performed by a qualified HVAC technician, licensed plumber, or trained fluid-system mechanic in accordance with applicable codes and equipment manufacturer guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 223\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.625 inches (40.87 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.875 inches (47.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches (3.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 90 Durometer (Extra Hard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.83 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZMSCH90223\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691786961202,"sku":"ZMSCH90223","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_c2615a2b-b216-484d-a853-5d6e80f5f17f.jpg?v=1788289669","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90223-o-ring-dash-223-nbr-90d-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
